For me, mind control is fun because of what fucked up things you can do as a result.
In the game Corruption,
https://f95zone.to/threads/corruption-v2-35-mr-c.1878/, you can mind control a family, then literally fuck the wife & daughter in front of the husband; he's mind controlled too, all while having a casual conversation at the dinner table.
Mind Controlled Jake, Husband of Emily: "How's the dinner Paul?"
*Paul fucking Emily, wife of Jake, at the dinner table* "Both the pork rump, and that of your wifes are absolutely fantastic Jake. Ohhh, and I can't wait to sample your daughter next!"
Mind Controlled Jake: "My family is so lucky to have a good and trusted friend like you."
However, IMO, the act of mind control doesn't come off as alpha or dominant, despite gaining total control, because you acquired that power without learning real social dominance.
Imagine being able to seduce the wife & daughter of a family without mind control, and still being able to fuck them in front of the husband, of whom you've destroyed and made submissive. IMO, that is real power, that is dominance, corrupting and destroying them mentally with their free will intact. Something like that would produce far more powerful erotic stimulation IMO. If you've ever played the Sims, you can walk into anyone's house and seduce the guys wife, all while he's there, and he's not mind controlled, but the husband is passive, all while you're hitting on his wife in front of him, that's EROTIC as fuck imo.
So, I like mind control, but I'm not a huge fan of it, because it ends up being very, very shallow in the end. You easily get the sex scene without proper mental build up, and that weakens the erotic impact of the sex scene, so it's arousing, but not in a way that really fucks the mind to produce those powerful feelings of lust. However, I don't think this is the case for everybody. Mind control can preserve the element of goodness, while you still get the sex. "Hey Jake, how was work?", while his daughter is sucking the MC dick in front of her dad, but the dad thinks nothing of it. As messed up as it is, there's still a sense of decency and normalcy. Without mind control, you can feel how much more evil and corrupt the sex scene can be, which might be too sadistic for a lot of people I'd think, because you'd feel the husband's suffering as he watches your MC plow his wife and daughter in front of him.
